Republican results

Mitt Romney has held on to win (apparently easily) in Massachusetts, his home state. None of that is a surprise but it does highlight a whiff of hubris in the McCain campaign, who had been campaigning in recent days in Massachusetts in a bid to humiliate Romney.

The gambit failed and the time taken may have left California exposed, which starts to look like the one thing that can keep Romney in the race.

Interestingly, Mike Huckabee seems even stronger in the South than expected: currently leading the early returns from Georgia, where pre-election polls suggested he would be third. That could be good news for McCain but it may also leave him even further indebted to Huckabee than he would like.
